table.txt

Hello,

for the attached table we would like to find the index of the max point of the variable NE8 within the range of (200,400) applied on the variable GDALT. This might be a simpel task and I am complicating it but if anyone can help.

Hi Salma,

My understanding is that for rows having GDALT in range 200-400 you would like to find the row where NE8 is maximum.

Please see if this code helps

txt = readtable("table.txt"); 
% I'm adding an Index Column, in case you specifically want the index
txt.INDEX = (1:height(txt))';
subTable = txt(txt.GDALT >=200 & txt.GDALT <=400, :);
% getting idx in the subtable using max function
[~,idx] = max(subTable.NE8,[],'omitnan');
% this row contains the required result. You can use the index from this
% row. 
result = subTable(idx,:)
